CAM FOR STAM P-MILLS.I

SPECIFICATION forming part of Letters latent No. 502,219, dated July 25, 1893.

Application filed March 28, 1893.

To all whom it may concern/.-

Beit known that I, ALBERT AMSBURY, of Keystone, in the county of Pennington and State of South Dakota, have invented a new and Improved Cam for Stamp-Mills, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved stamp mill cam, which is simple and durable in construction, and arranged for convenient application to the revoluble shaft, without disturbing the latter in its bearings or removing the other camsv on the said shaft.

The invention consists of certain parts and details, and combinations of the same, as will be hereinafter described and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the gures.

Figure l is a face view ofthe improvement. Fig. 2 is a plan view of the same. Figs. 3 and 4. are face views of the cam sections detached; and Figs. 5 and 6 are plan views of the same.

The improved cam for stamp mills is composed of the two sections A and B, provided with the usual toe part A and B respectively, and with the heels O and G respectively, forming the hub of the cam. From the heel C extend parallel flanges D and D', adapted'to engage, with their opposite faces, the top and bottom of part of the heel C, while'the rear faces of the said lianges D and D fit against flanges E and E projecting from the top and bottom of the heel O. The front, rounded edges of the Iianges D and D are adapted to abut on shoulders A2 and A3 respectively, formed on the cam section A above and below the heel C. In a like manner, the curved' edges of the flanges E and E it on shoulders B2 and B3 respectively on the cam section B. When the two cam sections are fitted together, as illustrated in Fig. 1, then the heel parts C and C form a complete hub and are also interlocked one with the other by the flanges engaging the respective Serial No. 467,948.

parts, as shown. It is further understood that the flanges E and E fit over part of the heel C', in a manner similar to that in which the flanges D and D it over part of the heel C.

In order to fasten the interlocking sections together, I provide two keys F and F of which the key F passes through an aperture in the liange D and then through a corresponding registering aperture in the heel O, to finally pass through an aperture in the lower ange D. The key F passes through apertures in the flanges E, E, and a registering aperture in the heel C, as illustrated in y the drawin gs.

.The cam sections A and B are applied to the shaft G previous to interlocking the same, the two sections being fitted over the shaft from opposite sides and then pushed together to interlock with their several parts, as above described, care beingtaken that the heel C engages, with its key-way, the key H on the shaft G. vWhen the two sections are thus tted, one on the other, and on the shaft G, then the keys F and F are driven into their respective registering apertures, so as to fasten the two sections firmly together, at the same time fastening the sections on the shaft. In case one or both of the sections are broken, the respective section of the entire cam can be readily removed, by first removing the keys and then removing the respective section or sections and replacing the same by new ones of a like construction. It will be seen that by this arrangement any desired depth of hub can be given to the cam to securely hold the latter to the shaft, and the cam can be readily applied at any time without disturbing the shaft in its bearings, or'
